' UNITED STATES PATENT. OFFICE.

SAMUEL B. LONG, OF SHELLSBURG, PENNSYLVANIA.

B RAKEf-SHOE.

SPECIFICATION forming part of Letters Patent No. 259,179, dated June 6,1882.

Application filed April 17, 1882. (No model.)

To all whom it may concern 7 Be it known that I, SAMUEL B. LONG, ofShellsburg, in the county of Bedford and State of Pennsylvania, haveinvented certain new and useful Improvements in Brake-Shoes forVehicles; and I do hereby declare. that the fol-' lowing is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a perspective view of thebrakeblock, with its shoe or rubber and clamp-bolts. Fig. 2 is a similarview of the block with the shoe removed, and Fig. 3 is a cross-sectionthrough the block and shoe.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to wagon-brakes; and it consists in animproved construction of the brake-block, to which the shoe-or rubber(which bears against the wheel in applying or setting the brake) isattached, having for its object to hold the shoe firmly at all timeswithout slipping, while at the same time it can easily be removed, whenrequired, for renewal.

In the accompanying drawings, A represents the brake-block, to the frontside or face of which is secured by bolts B B an angleplate, 0, the faceof which has a series of pro-. jecting teeth or sharp points, D D.

E E are clamp-bolts, which are inserted transversely through thebrake-block parallel to each other, and nutted at their outer ends uponthe back plate, F, of the brake-block.

G is the brake-shoe or rubber, which is held between the clamp-bolts EE, as clearly shown in the drawings. By tightening up the nuts of thelatter the teeth or pointed projections D of face-plate G are forcedinto the wood of the rubber, thus holding it firmly in place andpreventing its 'nioving either up or down, while the clamps, inconjunction with the teeth, prevent lateral or sidewise motion of theshoe upon the block. To detach or readjust the shoe, all that isnecessary is to loosen the clampbolts, when the shoe will readily comeoft without hammering. The shoe may be made simply from a flat piece ofplank, of suitable length and thickness, shaped to lit between theclamps, and does not require to be out or shaped with tapering sides andface, as it is not wedged upon but clamped to the block A.

Iam aware that it is not new to construct detachable brake-shoes withclamps by which they are fastened upon the brake block or beam, or tomake said block or beam with a notched or serrated face for the betterattachment of the shoe; nor do I claim such construction, broadly; but
